Be it known that'I, CLARENCE L. BROW'N, a citizen of the United States, residingat Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Temperature- Recording Devices, of which the following is a specification.

Thisinvention relates to improvements intemperaturerecording devices and is designed especially for recordmg thejtemperatures during the processo'f pasteurization of nected to an individualreceptacle or bottle milk, grape juice, beer-and other-liquids,

- The principal object of the invention is.

to provide an instrument which maybe concontaining the liquidto 'be pasteurized and will record the varying temperatures ,or

same as said receptacle passes tlirouglnthe' pasteuriz ng machine v Another ob'ect of the invention to provide aninstrument of v the abovefclas's of simplecompact construction, in which a re volving cylinder. carriesa-chart for receivingthe record;

With'the aboveand'other objects iniiview as will beunderstood, the invention consists :in'certain; combinations and arrangements ofthe parts hereinafter fully described in connection with the a ccompanying drawings illustrating a preferred embodiment thereof,

and the novel features of the invention will 1 be distinctly pointed out in claims. 1

the appended In the drawings like characters of reference indicate corresponding parts.

bottle containing a liquid 2 to be pasteuriaed by passing the bottle through a pasteurlzing machine in the ordinarymanner. H 1.

The invention consists of a 51111321. lea1r andjwater tight casing for inclcsing the operative parts, which is preferably. con,- structed of an annular base flange 3 and @a' corresponding dome flange it, each of which are oppositely grooved as indicated at 5 and, 6 forreceivmg the lowerfland upper cylinder 7.

Aa yjdesn-ed'number of hours may, be represented on the f chart. ,-;'1he chart is also divided transe .:verselyi by equally spaced degree or temperature I lines 27 preferably markedfas at 28 fromjlO degrees to 60 degrees. [The record line, ;indicating the varying temperatures vertically according to the 'temperatureof tension Tor-actuating said lever to cause the actuated relatively to the temperature of the liquid as follows. The pencil29 is held' in the bifurcated end 30 of a vertical arm,

31, which is pivoted at 32 to the free 'forke'dl endot a horizontal lever 33 pivotally sup-.

ported at its other end on a pin 34. carried by a pair of bearing lugs 35 projecting from the base flange 3. is 'held in normal position by means of a coiled balance spring 36, which depends from the'cupp'ed flange 12,, and-saidarm 3i a coiledspring 37 which connects the arm to said lever.

The horizontal lever '33.

on its pivot pin-34 {to actuate the pencil-29' the liquid 2' in the bottlel, by means of at plunger 38 which is pivoted to said lever "at 39-a1nd depends intothe upper portion ofa tubula-ryextension 40 depending from the} base flange-8 into saidbot-tle. The tubular;

extension 40 is enlarged at 'itsfree lower end i to *form a bulb 41 and contains a '-suitable substance 42 such as'mercuryythat will contract and expand relatively with the tem- =perature of the liquid '2 in said bottle and thereby force "the plunger upwardly -or allow "it to-descend.

Thebperation-ol? the device follows: As-.

suming that the instrument is attached to *bottle as-shown'in Fig. 1, and the'bottle containing liquid at a normal temperature is passed through a pasteurizing machine.

The chart illustrated in "Fig. 2hav'ing been 'fixed'tofithecylinder I5, the pencil 29 being "in contact with the chart at the intersection of its lowesthorizontalltemperatureline and one of the zero vertical time lines, and the and rising in the tubular 'extension forces the, plunger 3'8 upwardly. As the "temperature of the liquid in the bottle becomes cooler the *mercury relatively contracts,

thereby allowing the plunger to "descend.

Said expansion and contraction causes the pencilto move 'vertlcally, and asthe chart is traveling longitudinally, a line will be traced on said chart showing the temperature at which the liquid was pasteurized at any particular division of =time on the-chart.

In *this way an accurate record 'of-the vary ing pasteurizing temperatures is automatically obtained. v

ltis to be understood, that *s'light changes in the details of construction and arrangecylinder rotated bythe spring "motor so "that the chart will travel from said zero ment of the parts may be made within the scope "of the'claims, without departing from the spirit of the invention.

Having fully described my invention what I claim is:
